Blistr is a new card punch with two important differences to more traditional card punches. First, it is built like a pair of small pliers and therefore very easy to use. The pliers are a flexure design 3D printed from carbon reinforced nylon. (Starting design was created by BYU Compliant Mechanisms Research which I modified to fit my needs.) Second, this punch creates a bigger smoother blister than needle based punches. The tip is not sharp and therefore does not punch trough the playing card. For many this will be easier to feel than a fine needle prick. The blister is a half dome with about 1 mm in diameter. The exact depth of the impression can be adjusted with a 3/32-inch hex wrench.
If you place a blister in opposing diagonal corners or perhaps in all four corners of a card you can create a similar effect to a breather crimp - a key card to which it is easy to cut to. The advantage of the blisters is that they will typically remain active for a much longer time than a breather crimp.

This thing is ingenious. It looks as if it should be fragile until one realizes it is of one piece and there is nothing to fall apart. The blister it leaves is innocuous but quite visible/feelable. It is small enough
for the pocket so as to be used for impromptu miracles or those with a borrowed deck. However, a downside is that in order to hit the same spot, some external sizer will need to be made/jerry-rigged. These
exactly placed blisters are nice for, say, Bee Club Special, or Erdnase (Conjuring Arts) backs with criss-cross patterns. Raising one of the diagonals with a blister leaves a broken or non-straight line to be seen, rather than a more obvious blister. The Pinpoint Pegger with a blunted pin may do a better job (or at least be easier) because of the
ability to lock in 3D coordinates.
